实现VariableSizeList 通过上一小节,我们已经把通用的代码逻辑放到了createListComponent.js中了,我们按照上面分析的思路一步步实现 组件模板 代码语言:javascript 代码运行次数:0 运行 AI代码解释 constVariableSizeList=createListComponent({getEstimatedTotalSize:()=>0,
importReactfrom'react';import{VariableSizeListasList}from'react-window';constrowHeights=newArray(1000).fill(true).map(()=>25+Math.round(Math.random()*50));constgetItemSize=(index:number)=>rowHeights[index];constRow=({index,style})=>(Row{' '}{index});constExample=()=>(<Listheight={1...
AI代码解释 import{forwardRef,useState}from'react';import{flushSync}from'react-dom';// 动态列表组件constVariableSizeList=forwardRef(({containerHeight,getItemHeight,itemCount,itemData,children},ref)=>{ref.current={resetHeight:()=>{setOffsets(genOffsets());}};// children 语义不好,赋值给 Componentc...
yarn add react-window 安装完成后,在你的组件中引入React Window: jsx import { FixedSizeList } from 'react-window'; 现在,我们可以开始使用React Window来渲染大型列表或表格。 渲染大型列表 在React中,渲染大型列表是一个常见的性能问题,特别是在移动设备上。传统的渲染方式往往一次性将所有列表项都渲染出来,...
The snippet below shows a basic example of how theInfiniteLoadercan be used to wrap either aFixedSizeListorVariableSizeListfromreact-window. // This value is arbitrary.// If you know the size of your remote data, you can provide a real value.// You can also increase this value gradually...
variableThis type is preferred when the sizes of the items in the list vary. Supply theitemSizeGetterwhen possible so the entire length of the list can be established beforehand. Otherwise, the item sizes will be cached as they are rendered so that items that are above the viewport can be...
从官方的 Demo 来看,AntD 提供了一个 components 属性,通过传入一个对象,在其 body 属性中给到一个 ReactWindow 提供的虚拟化组件,以实现需求 ... // VariableSizeGrid is a component provided by react-window const renderVirtualList = (rawData, { scrollbarSize, ref, onScroll })=> <VariableSizeGrid...
Basic the idea here is to set the ref from react-custom-scrollbars so the react-window AutoSizer or VariableSizeList will work with this approach, as in this example https://codesandbox.io/s/react-window-custom-scrollbars-t4352 @ranihorevcan you also share Code Sandbox example?
